Suggestions for microprocessor module

Jesus christ ... get a breadboard and a 4-5 pin header or replace breadboard with a stripboard if you have soldering iron - example https://www.ebay.com/itm/376176460955  or https://www.ebay.com/itm/398087349511

You have that Microchip SNAP for 10-12$ that can program PICs, Atmel parts, and some other ICs, you need 4-5 wires to the board to program the micro.

You have 800+ DIP packages , PICs and Atmel , you can program all in assembler :  https://www.digikey.com/short/j2qthwmp

Some of the more old PICs and low pin count (ex maybe pic10f) may not be supported by the SNAP but older programmers will work (basically SNAP only works with chips that can be programmed using low voltage, all the more modern ones support low voltage programming)

OK. So if I want to go this route, could you maybe supply specifics?
Like specific chips, programmers, software? So I don't have to hunt them down?

I still have some SX-28 chips, no programmer, but they don't have enough I/O pins, so time to move on to something else.

I do have breadboards, soldering iron, all that: however, I like the idea of a dev board w/chip to simplify things. (Previously I assembled my SX-28 projects on perfboard, soldered.)

So I have not done anything like this, but if I were to do so, I think I would look at an Arduino. A nice convenient dev board with peripheral interfaces on it, a competent microprocessor, and plenty of ways to program it.

Specifically, whilst the majority of the Arduino programming ecosystem is based around C language, for the OP's requirements, the Arduino can definitely be programmed in assembly, which raises another important question.

Will the OP be relying on assembly language modules and libraries developed by the community?  Or will the OP be coding assembly from scratch?

If the OP is looking for community assembly code examples and snippets, they may struggle to find a large codebase beyond PIC.  Pretty much everyone has moved on to C.

The lack of a large assembly codebase also means less training material for AI tools, which may be more error prone with generating assembly language, compared to AI generated C code.  This may be a moot point if the OP won't be using AI.

From scratch.

"Libraries? Libraries? We don't need no steenkin' libraries!"
I know how to roll my own stuff. Not doing anything spectacular on a dinky micro, leave that stuff for my PC.

And no goddamned "AI" either.
